So, if your application does a great deal of file I/O on the nodes, you
might consider implementing a service network through the second network
ports.
this is convenient, since if you use two nics with different subnets,
traffic will be segregated and non-interfering.
However, if your application needs more total bandwidth on a
single network, you will want to go with channel bonding. If the
besides being slightly trickier to configure, it also only gives you
higher _aggregate_ bandwidth. any single flow between a pair of IPs
will not be faster than a single link. bonding/teaming/link-aggregation
is mainly useful for inter-switch links and hosts like a fileserver
which are effectively a hotspot and can take advantage of multiple
concurrent flows (again, where each flow is no faster than 1 link.)
in other words, there's no standard "raid0 of nics" ;)
